"Harley Quinn's got her own definition of family. The gang of misfits, weirdos and two-fisted freaks she's assembled in her Brooklyn crash pad are all the family a reformed psychotic super-villain could ask for, ya know? But that's all about to change. The Mistress of Mayhem is about to face the biggest shock she's seen in years ... a visit from her parents. That's right, folks--Mr. and Mrs. Quinzel are in town to take a bite of the Big Apple and meet their li'l monster's new crew, from her gal-pal Poison Ivy to her super-friend Power Girl and more. And since "alternative lifestyle" barely begins to describe the vida loca that Harley's livin', our bat-wielding bombshell's more than a little mortified. But it turns out the crazy apple doesn't fall far from the twisted tree. Harley's mom and pop have quite a few skeletons in their own closet and no shortage of tricks up their sleeves. And before Harley's big birthday blowout, every secret's about to come out!"-- Provided by publisher.
